Which of the following would be produced by meiosis?
red blood cell
cells of the stem in plants
sperm cell
epithelial cell

Sperm cell.

Explanation:

Two main types of cell division cell division are mitosis and meiosis. Meiosis is the process of cell division in which a single cell divides into the four daughter cells. This division is also known as reduction division.

The meiosis takes place in the gamete or sex cell. Sperm and ova are produced by reducing the chromosome number upto the half so that zygote can restore the diploidy. Hence, sperm cells are produced by the process of meiosis.

Thus, the correct answer is option (3).

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
